Russian Coal Mine Explosion

Russian Coal Mine Explosion
MOSCOW (Reuters) - Rescue teams re-entered one of Russia's
largest coal mines on Sunday in a bid to find 83 people
trapped underground by two methane explosions after a build
up of gas halted the search for most of the day, officials
said.

Twelve people died and another 41 were injured in two
methane explosions at the Raspadskaya mine in Siberia's
coal-rich Kemerovo region 3,000 km (1,850 miles) east of
Moscow late on Saturday, the Emergencies Ministry said.
Sixty-four miners and 19 rescuers were unaccounted for
underground over 24 hours after the first explosion just
before midnight (1700 GMT) on Saturday. Both explosions were
caused by methane gas build-up, the ministry said.

The number of dead has in the meantime increased to at least
60 according to CNN, with another 30 still missing.

The GCP event was set for 16:55 plus 7, hours GMT. The result
is Chisquare 25521.474 on 25200 df, for p = 0.077 and Z =
1.429.

It is important to keep in mind that we have only a tiny
statistical
effect, so that it is always hard to distinguish signal from
noise. This means that every "success" might be largely
driven by chance, and every "null" might include a real
signal overwhelmed by noise. In the long run, a real effect
can
be identified only by patiently accumulating replications of
similar analyses.
